THE ATKINS DIET
So I was watching a documentary this morning (New Years Day) on the Atkins diet, and thought it would be a good idea to give you an idea of it and whether it's good for you.
Basically this diet has been around for the last 30 years and it would be surprising if you knew anyone that has never heard of it.
The Atkins diet is a very low carbohydrate and high protein and fat diet. The idea is that when the body is low on carbohydrate (our main energy source) it will turn to stored fat in order to provide energy. This type of diet has been advocated by many celebrities, and it has been plain to see the weight loss results it has produced, initially from Jennifer Aniston and also Renee Zellweger.
Let's think about the role of carbohydrate; it is our main source of energy, yielding only 4kcals per gram, compared to fat which yields 9kcals per gram. It also contains fibre, which I describe as the shell or skeleton of plants. Fibre is required to bulk up your food, slowing digestion time allowing full absorption of nutrients and also cleansing of the small and large intestines, research shows that fibre has the ability to reduce risk of some cancers.
Now onto fat, we do need it; it plays a really important role in keeping us healthy, and optimum functioning. However, the Atkins diet doesn't focus on our healthy fats; such as poly-unsaturated, mono-unsaturated and our EFA's (essential fatty acids omega 3 & 6), as it encourages plenty of animal protein and saturated fat, for example; bacon, beef, sausages, fried eggs, full fat milk, cheese and butter. An increase in any food will equate to weight gain; that is fact, whether it is fat, protein or carbohydrate. The argument lies around the fact that although fat has over twice the calories of carbohydrate; we are less likely to consume as much, and as it is consumed with protein; this may leave us feeling fuller for longer. Eat a portion of refined carbohydrate and you'll find that you'll be going back for more very soon, and therefore consuming more in the long run. The reason for the urge for more is due to the spike and then dip in insulin levels; responding to the sugar in the blood needing transportation into the cells of the body, this is the role of insulin, and when insulin levels drop so do we, leaving us feeling sluggish and needing more. This can easily lead to excess calories being consumed, weight gain, obesity and increased risk of developing type 2 diabetes, known as insulin resistant diabetes.
One way to increase our cholesterol levels is to consume saturated fat, of course this is not desirable. Cholesterol plays an important role in producing hormones and cell formation, our liver makes cholesterol, therefore it is unnecessary to focus on consuming more or increasing our levels. The big problem lies here; increased cholesterol levels means that there is more circulating in the blood, this means more can attach and settle on the artery walls (our blood vessels), this build up causes blood pressure to rise and a hardening of the muscular artery wall. This causes blood to pass through at high pressure (hypertension), and if the build up of cholesterol (known as atheroma) breaks away; this can cause a blockage in blood vessels around the heart and brain, resulting in a heart attack or stroke respectively.
I know many people who swear by a high saturated fat diet, and have no health issues. Does the Atkins diet work? Yes, absolutely, but is it a safe and sustainable diet? Absolutely not!
It is important to be aware of these issues before you make your own mind up and give it a go.
